 # Flashing from the Transmitter
 
-For radios running erskyTx and OpenTX, there is an option to flash a precompiled firmware file to the multiprotocol module using the transmitter's Bootloader mode.
+For radios running erskyTx and OpenTX, there is an option to flash a precompiled firmware file to the multiprotocol module:
+- OpenTX: using the SD card browser
+- erskyTX : using the transmitter's Bootloader mode.
 
-## Tools required
-* A compatible transmitter running an erskyTx bootloader v2.9 or newer. This is true for both OpenTX and erskyTx.
+What you need:
 * A precompiled multiprotocol firmware file (.hex for Atmega328p or .bin for STM32)
 * A **Flash from TX** bootloader installed on an Atmega328p or STM32 multiprotocol module
 * A means to get the firmware file onto the transmitter's SD card
 
-## Radio bootloader and apps
+## OpenTX 2.3.3 or newer
+1. Copy the firmware file to the radio's SD card - it doesn't matter where you put it
+1. Switch the radio on normally and use the radio menu to locate the file on the SD card
+1. Highlight the file and press the ENTER button
+1. Choose Flash internal module or Flash external module as appropriate
